Abstract

The method for concentrating an oxygen isotope or isotopes of the present invention combines the step of concentrating 17 O and/or the step of depleting 18 O that utilizes photodissociation of ozone by a laser beam with an oxygen distillation step that concentrates the oxygen isotope. At this time, it is preferable to carry out a step of isotope scrambling in addition to the above. When both a step of concentrating 17 O and a step of depleting 18 O are carried out, whichever thereof may be done first prior to the other. Also these steps may be placed either before or after the oxygen distillation step. Moreover, at least one of said oxygen distillation step, the concentrating 17 O step, the depleting 18 O step and the isotope scrambling step is preferably carried out twice or more. According to the invention, low abundance ratio oxygen stable isotope 17 and 18 can be concentrated into high concentration effectually under technical scale.

Background technology
Oxygen stable isotope 16O, 17O and 18Among the O, owing to have only 17O has nuclear spin, therefore uses 17The compound of O mark is used for researchs such as the structural analysis undertaken by nuclear magnetic resonance, and is used as tracer in fields such as chemistry and medical science.In addition, the diagnostic agent of the positive electron laminagraphy diagnosis of using as the inspection that is used for tumour etc. (PET) 18The raw material of FDG (the PET contrast preparation that obtains with the fluorine 18 labelled with radioisotope FDGs of positive electron release nucleic), the utilization of expectation in medical field.
That is, 17O and 18O is an isotope useful on the industry, still, because natural abundance ratio is very little, need concentrate from the compound that contains oxygen atom when using it 17O and/or 18O.

But, in the method for non-patent literature 1 record, if consider that yield then exists resulting 17Be limited to the problem of several atom% degree in the O practicality, in the method for non-patent literature 4 records, concentrate by this method for concentration 17O is as H 2O or O 2On market, sell, but exist it to concentrate the inadequate problem of amount.
In addition, in non-patent literature 2, patent documentation 5 and the patent documentation 6 method of record also exist enrichment factor insufficient, also do not establish the problem of the technology of carrying out under the commercial scale.
Further, in the method for non-patent literature 3 records, can in remaining ozone, concentrate 17O and 18O confirms the isotope effect that ozone decomposes, but is not the enrichment factor that can be used in the isotopic separation degree.In addition, do not establish the technology of carrying out under the commercial scale yet.
On the other hand, the method for record is the method that is expected in industrial realization in the patent documentation 2,3 and 4, but because there is overlapped part in the laser absorption wave-length coverage of each ozone isotopic molecule, is particularly containing 17When the abundance ratio of the ozone molecule of O is little, though want by laser optionally only the disassociation contain 17The ozone molecule of O also can dissociate simultaneously 16O 3Etc. the bigger isotopic molecule of abundance ratio.Therefore, existence is difficult to obtain effectively high concentration 17The problem of O.
Below, from being elaborated with the method for related angle of the present invention to patent documentation 1 record.
Contain 16O, 17O and 18Its vapour pressure of the isotopic molecule of O (boiling point) is all very approaching, contains 17The isotopic molecule of O is to contain 16The isotopic molecule of O and containing 18(vapour pressure or boiling point exist the inter-level of the isotopic molecule of O 16O and 18Between the O), 17The natural abundance ratio of O is about 370atomppm, less than 18The 2000atomppm of O.Therefore, undertaken by distillation as patent documentation 1 is disclosed 17In the method for concentration of O, exist to be difficult to obtain effectively high concentration (for example more than the 5atom%) 17The problem of O.To this, carry out specific description by following example.
Figure 22 is used for the compound that contains oxygen atom (H for example 2O, NO, O 2Deng) distill, improve 17O or 18The skeleton diagram of the destilling tower 1 of O isotopes concentration.In fact, in most cases because the height (theoretical cam curve) of the destilling tower that requires is very high, the destilling tower that therefore actual device uses a plurality of destilling towers to be in series usually carries out a series of distillation procedure, but simplify at this, represent with a destilling tower.
Near cat head pars intermedia is supplied with oxygen to destilling tower 1 isotopic abundance ratio is raw material F (for example, the H of natural abundance ratio as shown in table 1 2O, NO, O 2Deng), collect concentrated from tower bottom 17O or 18The product P 1 of O.In addition, also exist, compare the tower pars intermedia of tower bottom side with the supply position of raw material F and collect concentrated with product P 1 17O or 18The situation of the other products P2 of O.Compare with raw material F and to have reduced 17O or 18The waste gas W of O discharges from top of tower.
[table 1]
Isotope Atomic weight Abundance ratio
16O 17O 18O 16 17 18 0.99759 0.00037 0.00204
Tower bottom at this destilling tower 1 concentrates 17O, when collecting product P 1 at the bottom of the tower, the isotopes concentration in the destilling tower distributes roughly as shown in figure 23.The longitudinal axis of Figure 23 is represented the concentration (atom%) of each oxygen isotope, and transverse axis is represented the height of destilling tower, among this figure afterwards too.Product P 1 17Though the enrichment of O according to height (theoretical cam curve) difference of destilling tower, is generally the scope of 0.2～5atom%.In the example of Figure 23, product P 1 17The O enrichment is about 1atom%.
On the other hand, in order to obtain highly enriched degree (for example more than the 5atom%) 17O, the destilling tower of needs higher (theoretical cam curve is many).At this moment, as shown in figure 24, because than 17The composition that the O boiling point is high 18O is condensed into high concentration at tower bottom, tower bottom 17The O enrichment reduces, 17The concentration of O is formed on the distribution that the pars intermedia of tower has maximum.That is, destilling tower 1 inside can be divided into from raw material F supply with the position to 17Till the O concentrate P2 assembling position 17The interval A that the O enrichment increases, and from 17O concentrate P2 assembling position arrives 18Till the O concentrate P1 assembling position 18The interval B that the O enrichment increases is in order to make 17O concentrate P2 assembling position 17O enrichment bigger (for example more than the 5atom%) must increase the height of interval A and interval B, and this method for concentration can not be realized industrial as far as possible.
Further, distil process needs a large amount of liquid column reserves in installing on its principle, thus exist for natural abundance than being at most the 370ppm degree 17O is condensed into high concentration (for example more than the 5atom%), and the starting time of device needs above problem for a long time of several years.
For the above reasons, we can say only will by distillation 17O is condensed into high concentration (for example more than the 8atom%) and realizes in industrial being difficult to.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of 17The O method for concentration, can be under commercial scale effectively and high concentration concentrate the very little oxygen stable isotope of abundance ratio 17O.In addition, provide with 17When being condensed into high concentration, O also can concentrate 18The method of O.

Specifically, this method is to concentrate by distillation at low concentration region (for example 370atomppm～0.2atom% degree) 17O, this low enrichment that will obtain by distillation again 17O further concentrates by separation by laser, thereby obtains high concentration (for example more than the 5atom%) 17O.
In addition, this method is removed effectively by the separation by laser device that is connected with this destilling tower and is being concentrated by distillation 17Become obstruction during O 18O promotes in this destilling tower 17O concentrates.In addition, this method obtains ultrahigh concentration with the combination of these methods, for example more than 70% 17O.
Among the present invention, use separation by laser device 17There are two kinds of methods in the O method for concentration.
That is containing in ozone gas, 16O, 17O and 18In the ozone molecule of O, will optionally decompose and contain 17The ozone molecule of O obtains 17The O concentrate oxygen separated from above-mentioned containing each isotopic ozone gas, thereby concentrated 17The method of O; And will optionally decompose and contain 18The ozone molecule of O obtains 18The O concentrate oxygen was removed from above-mentioned containing each isotopic ozone gas, thereby reduced 18The method of O.
Among the present invention, by concentrating to above-mentioned 17The operation of O and/or minimizing 18The operation of O makes up with the operation of distillation oxygen, can carry out effectively 17O concentrates.At this moment, by further adding the operation of carrying out the isotope conversion, can more effectively carry out 17O concentrates.
In addition, concentrate 17The operation of O and minimizing 18The operation of O both the time, the order of carrying out is not limited especially.In addition, these operations can be carried out arbitrarily in the front and back of the operation of distilling oxygen.
Further, by to the operation of distillation oxygen, concentrate 17The operation of O, minimizing 18The operation of O and at least a operation of carrying out in the operation of isotope conversion are carried out more than twice, can more effectively carry out 17O concentrates.
In addition, concentrate high concentration from feed oxygen 17During O, concentrating 17The operation of O and minimizing 18In the operation of O, separation from feed oxygen, recovery high concentration 18O.Thus, obtain high concentration 17Also can obtain high concentration in the time of O 18O (for example more than the 20atom%).
For what obtain by the present invention 17O concentrate oxygen (for example more than the 5atom%) or 18O concentrate oxygen (for example more than the 20atom%), according to conventional methods, for example, the hydrogen with adding after the argon diluent corresponding to this oxygen amount reacts under the temperature more than 80 ℃ in platinum catalyst, and can make oxygen isotope thus is that 1atom% is above 17The O condensed water or 18The O condensed water.
＜the first embodiment 〉
The most basic embodiment of the present invention, promptly first embodiment skeleton diagram as shown in Figure 1.Present embodiment is used to have connected and is used to distill oxygen and the device of isotopic destilling tower 1 of separated oxygen and separation by laser device 2 is characterized in that, 17The low concentration region of O carries out the phase I by distillation 17O concentrates, and for example exists 17O reach 0.2atom% above after, carry out separation by laser as second stage 17O concentrates.Thus, can concentrate effectively 17O.
Raw material F is fit to use ultra-high purity oxygen.As ultra-high purity oxygen, for example preferably from tonnage oxygen, remove argon, hydrocarbon etc., significantly improve the ultra-high purity oxygen of the chemical purity of oxygen.In addition, as the oxygen destilling tower, the destilling tower that also can use a plurality of destilling towers to be connected in series to form substitutes destilling tower 1.On the other hand, for the filler in the destilling tower, any one of service regeulations filler and irregular filler can obtain identical effect.
